a quilt pattern makes a quilt that is 48 inches by 60 inches.if you want to make the quilt 1/3 smaller how wpuld you find the new dimensions? what would the new dimensions be?

Answers

Answer 1

Answer: 60/3=20 and ad 48in

343cm³

____________________

Step-by-step explanation:

total surface = 6r² ⇔ 294=6r²

Then, r²=294÷6=49

Then r=√(49)=7

Therefore the volume = r³=7^(3)=343cm³.

_______________________________…

Answer:

total surface area=6x^2

area=x^3

6x^2=294

x^2=294/6

x^2=49

x=SQR(49)

x=7

x^3=7^3

area=343

13. Which of the following is the graph of y = 3(1⁄5)x?

Answers

Answer:

Second graph

Step-by-step explanation:

The second graph is the correct one. Why? because the y intercept is (0, 3), and also because the base, 1/5, is between 0 and 1, which leads to a decaying exponential graph.

Is the elevation halfway between the peak of Mount Ojos del Salado and the Atacama Trench above sea level or below sea level? Explain without calculating the exact value

Answers

I'm pretty sure it's below sea level because the trench is much farther down than the height of the mountain so if you were to find the middle it would have to be below sea level... I hope this helped :0

Which of the following equations best describes a square root function that is reflected across the x-axis and has a vertex of (−4,2)?A. $y=√(-(x-4)) +2$

B. $y= -√(x+2)-4$

C. $y=-√(x+4) +2$

D. $y=-√(x-4) +2$

Answers

Answer:

Step-by-step explanation:

Rather than picking, let's try to construct one from the description.

reflected over the x axis means - $√(x)$

the vertex is usually at (0,0), now how do we move a graph? or in other words translating it.

To move left and right you use $√(x-h)$ where if you subtract h you move right and if you add h you move left. we go from (0,0) to (-4,2). so 0 to -4 is 4 left, so that means we add 4.

To move up and down we use $√(x)+v$ Here if v is positive you move up and if v is negative you move down. going from (0,0) to (-4,2) it moves up 2

So now we put them all together $-√(x+4)+2$ And if you look, C matches that exactly.

Draw an example of a shape that has at least one right angle one angle less than a right angle and one angle greater that a right angle label the angles

Answers

Answer with explanation:

We can consider a quadrilateral in which two angles are right angles i.e. the measure of two angle is 90 degree and one angle is obtuse angle i.e. whose measure is greater than 90 degree but less than 180 degree and a acute angle i.e. a angle whose measure is less than 90 degrees.

The figure is attached to the answer.

The figure is in the shape of a trapezium.

The angles are called acute obtuse and right angle.
